Be it known. that L'Jmiss C. Lewis, a ii. of the Unit d Stetes, residing at and in the county Cumberland and 1* ii'lleinc, have invented new and useimprovements in -VehicleElevsting l Aieciienism of which the following is e specificetioii,

of this invention is particularly (l f0. use in connection with entomoii Where it is often necessary to reuse the to 'i'emo've tire for repairs, or to re i the Wlieei sail "the tile, ail as Well iiiic'w'zi to those skilled in this art.

The object of this invention is to perform ,ecpei'atioiis with the least possible iel or the object of the invention is to provide a i of the ci'ieiscter set forth which may as pereteci Without the expenditure of e great amount of strength eiidwitliout soiii'ng clothing or hands of the user of the these enrls the invention consists in the "iiioi-ion eiiri arrangement of parts set n tliefollowing specification pari vein ecl cutin the claims thereof.

Kii'lilw Way between the opposite sifies theieoii front end of the shaft 18 is rotetebi z mount in a bearing 19 ieit to the fro ezlethe ieck is is is the 31,2 3 1 ately acijecent and. at the reel of the bearing 1 "the ice-st expenditure of time, and

in automobile with my.

medie'teiy adjacent said bearing 19 enci at the rear thereof. The rear end of tie shaft 18- is rotatably mounted in ii bearing 20 which is fastened to the housing 1 1-, and the jack 17 is fastenei to the shaft 18 immedi- 20. The jack 1? is a pneumatic jack consisting of ecyiindei" 21, see 4, in which ismcunted a piston 22 having a pistonrod 23 fest tl'ieretc and extenciiiig downwardly therefrom through the head 2 of said cyl- 65 index; To the lower end of the piston rod 23 is festeneii a base plate A spring 26 1 encircles the piston rcol and beers at one end. against the head 24 and at the other eiicl against the piston 2%. The upper end of the bore oi the cylinder 21 isfccnnecieai by a port 27 to the interior of the hollow shaft 18; The front end of the shaft 18 is pro w eel with email veive 28 of any suitable sty'ie, but preferably of' theseme construction and. operating in the same manner as the air valve Well known to those skiiled in the art, which is provided on. pneumatic tires for automobiles. This air valve end shaft 18 to which it is attached may be connected to 8 any suitable scarce of air uncler pressure, such es, for example, an air pump which is provided. with many of the automobiles J now on the market. or said pipe may be 1:01 nectecl by a flexible nose to e tank of compressed sir caniecl by the automobileflbut notn showiiin the drawings. A flexible ose 29 of this character is illustrated in dotted lines, Fig. 1, as attached to the front end of the hollow shaft 18. The jack 16 is of similar construction and operated in the same man- T3931 as the jeck'l? except that the bore of the cylinder of sairi jack is proviclecl with an air valve 30 of similar construction to the i A valve 28, end. when it is tlesired to operate the we 16 the hose 29 is attached to this an valve 39. it will, tliei'ercre, be seen that I each of the jacks 16 and 1'5 may be operates inclepeincieiitiy cf escii ether.

In orciei' tc lOWQ? time jecizs 16 am; 1'? into QVBTSiiiVE pcsiticiies illustrated. in

i theii'iopei'eti've positioii' ii'liistieteii in the iioiicw 18 has hereinbefore described is as follows :--Assuming the jacks 16 and .17 to be in the raised position illustrated in Fig. 2, the

socket wrench 37 is attached to the upper end of the shaft 34L and rotated by the operator in the pro er direction to rotate the shaft 18in the dlrectionof the arrow a,

2. This will lower the jacks to a verticalfposition. If it is desired to raise the froiit wheels 11, the operator connects the hose 29' to the valve 30 and the hose is connected to a punfp in the automobile, or if in a'garage, the air'hosefrom the air compressor is attachedto the valve 30 which causes thevbase plate 25' to move downward y and after it contacts with the ground .or flo 1r upon which the automobile is rest ing, further downward movement of said base plate 25 will cause both wheels to be elevated fromv the ground at-the same time.

Upon completing thework which is contemplated, the operatorremoves the hose from the valve 30 and pressing upon the air valve stem allows the air to pass out of the cylinder of the j'ack16 and the spring 26 of said jack will then cause the piston 22, piston rod 23 and base plate 25 to move upwardly away from the ground or floor. The operator then rotates the wrench 37 in the proper direction to rotate the shaft 18 in a direction reverse to that of the arrow a thus bringing the parts into the rela-.

tive positions illustrated in Fig. 2.

When'it is desired to raise the rear wheels 12 from the ground, the same operation is performed to position the jack 17 and com pressed air is forced thefeinto by attaching operated to allow the compressed air in the hollow shaft 18 and in the jack 17 to pass outof the front end of said shaft. The parts are then positioned as illustrated in Fig. 2 in the manner hereinbefore set forth.

It will be noted that the shaft 18 belng, rotated by a worm gear mechanism will be locked in position wherever it may be 1 'vehicle with its axia desired by rotation the shaft\34 and by means of the socket wrench 37. l
